ORE-'CRUSHEFL SPECIFICATION forming part of Letters Patent No. 464,083,dated December 1,1891.

Application filed May 4, 1890. Serial No. 342,589. (No model.) y

To all whom/lit mag/concern.-

Be it known that we, GEORGE RAYMONDand States, residing at Chicago, inthe county of Cook and State of Illinois, have invented cer' tain newand useful Improvements in Ore- Crushers, of which the following is aspecili-` cation.

Our invention relates to` a machine for crushing ores or othenmaterialswherein a crushing-head operates in conjunction with a casing to crushthe ore or other Vmaterial between them.

More specifically stated, our invention relates to a crusher wherein anupright shaft carries on one end a crushinghead surrounded by a casingto confine the material, the other end of said shaft being caused togyrate. The crushing-head is left free, and `the material falls betweenthe head and surrounding cas-` ing and is crushed 'between theiropposing surfaces, the materialY itself forming a'ful-Q crum over whichthe head rocks,` and the ma# terial, when reduced, dropping out at thebottom of the crushing-chamber.

In one form of construction we employ a suitable base, on which aremounted vertically in proper bearings two shafts, on the lower ends ofwhich are driving gears enmeshed with pinions carriedk upon a rotatingshaft, and near the middle of said Yupright shafts are providedenlargements to form eccentrics whichoperate within sleeve-bearings oneither end of a` driving-beam, and the latter is'pro7 vided between theeccentricswith a suitable bearing to receive the end ofthecrushingshaft, a hollow column extending centrallyA above the base andthrough which thecrushing-shaft is passed, an annular frame formedintegrally with or bolted to the hollow column and having on itsinterior a lining to form the crushing-surface surrounding thecrushing-head carried upon the upper end of the crushing-shaft, and ahopper in which the material is placed and from which it feeds downbygravity into the crushing-chamber. The driving-beam is preferablysuspended by means of rods depending from the hollow column, and theserods are made adjustable, so

5o as to raise or lower the crushing`head,where by to regulate thefineness of the material on line 3 3 of Fig. l.

ing-head in the form of the frustum of a globular body where finecrushing is desired; but where only coarse work is to be done thecrushing-head may be in theforni of a frustum of a cone and surroundedby a casing whose walls are in the form'of the frustum of two conesjoined at their smaller ends. In another form of construction the headis mounted on the lower end of the shaft and its other end is gy'rated.I

In the accompanying drawings, Figure l is an. end elevation of themachine; Fig. 2 is a side elevation. Fig. 3 is a verticalI section Fig.4 is a plan below the line 4 4 of Fig. 2. Fig. 5 is a Ysectional detailtaken on line 5 5 of Fig. 2. Fig. 6 is the same on line 6 6 of the samefigure. Fig. 7 is a plan view of the driving-beam. Fig. 8

isa sectional detail showing `the crushing. .head of the machine inmodified form. Figs.

9 andlO are respectively side and sectional elevations of a crusher, inwhich the crushing-shaft is geared at its 4upper end and the head andcrushing-chamber are at the lower end of the shaft; and Fig. ll is across-section of the upper part of the crusher shown in Figs. 9 and l0and taken at' a right angle to Fig. 9.

In the drawings,.Figs. 1 to 8, inclusive, A indicates a suitable woodenor iron base, upon which isl mounted a rotatable driving-shaft B,carrying pinions b Y), a pulley B', and a lbalance-wheel. l Mounted uponthis frame 4areth'e bearings CC to receive the eccentric- I-I IIrepresent suspend-ing rods or bars whose upper ends are passed throughapertured lugs Il and have the securing and adjusting nuts h. These rodspass downwardly through openings in the hollow column, and their lowerends are passed through apertures in the driving-beam I. This beam isparticularly shown in Figs. 3 and 7 of the drawings and is a skeletoncasting having formed cen- IOO .shown in the preceding figures.

brate with the shaft.

trally thereof a box l and at each end thereof bearings to receive theeccentric portions (l of the shaft D. i

J represents the crushing-shaft, whose lower end is seated within thebox l and preferably surrounded by a bushing j. The upper end of thiscrushing-shaft projects above the top of the column F and bears thereona crushing-head K, which is preferably made separable from the shaft, sothat it can be replaced when"worn, and which may have a smooth orcorrugated surface, as desired.

L is an annular frame, which may be formed integrally with or bolted tothe upper part of the column, and which is provided with the lining M tofornia crushing-surface, and N is a `hopper from which the material isfed.

By referring to Figs. 5 and .dof the drawings, it Will be seen that theannular frame L is con-nected to the central column by means of the ribsZ,which will preferably be thinned yoff on their upper surfaces, asclearly show-n in Fig. 5, to prevent vlodgment of the. material andproviding the discharge-openings L between them. An annular receptacleor bin O surrounds'the column and will be provided with one or moredischarge-spente O for the discharge of the crushed material. Thisreceptacle is cast in separable pieces, as shownl in Fig. 2, so ras tobe bolted around the column, and the spout or spouts are cast integrallyWith the sections. The form of crushing-head K shown in Fig; 3 isadapted to fine crushing and is substantially in the shape of afrustumof a sphere, and the surrounding casing has concave walls correspondingthereto. `The form of crushing-head shown in the remaining figures andparticularly illustrated in Fig. 8 is in the form of a frustum of aconeand is adapted to the crushing of large stones by making the surroundingcasing flaring at the top, the finer reduction taking place as thematerial is discharged.

In Figs. 9, 10, and 11 of the drawings a crusher is shown in which thecrushing-chamber is arranged at the base of the machine, and the shafthas the crushing-head provided also at its lower end and its upper endis gyrated by means of the driving-beam,which is operated bysubstantially the same gearing The driving-beam in this case issupported by the column F; but the shaft is hung by the rods H,connected to the lugs H', which in this in- The upper ends of these rodsare connected to a head-block H, which has a ball-aiid-socket bearing,as shown at 7i', Figs. l0 and l1. lThis bearing permits the rods to rockor vi- In this construction the hopper N surrounds the lower end lof thecolumn F. and the inaterialniay discharge into a-suitable receptacle orspout beneath the machine. The principle involved in the use of the twoconstructions is precisely the saine and the structural adaptations areonly very slightly different. We regard both forms as beingsubstantially the same and therefore equally Within the scope of ourinvention.

In operation the material is placed 'Within the hopper and falls down bygravity between the crushing-headand the annular lining. Thedriving-shaft being put in inotion, the eccentrics will cause thedrivingbeam to gyrate and impart a corresponding motion to the end ofthe crusliing-shaft opposite the head. The otherend of this shaftcarrying the crusliing-head being left free, it will center itselfwithin the crushing-chainber, and the material falling` down between itssurface and thesurroundinglining will be crushed on either side of thehead. Y.This results from the fact that the material inwerkingits waydown after being partly reduced will be wedged between the lowerendofthe crushing-head and the surrounding4 casing, and as the shaft ismoved this material forms a fulcruin over which the crushing-head rocks,thus further reducing the material forming the ,fulcrum, while at thesame time 1 the upper end ofthe head forms the initial reduction byimpingng upon-the coarsernlaterial between it and the surroundingcasing, and the lower end crushes the material on the side that part ofvthe head approximates.

This construction and method -ofworking secures'important.advantages,which may be summarized aszfollows: The crus-hingis effectedon oppositesides of thehead `simultaneously, alternating withtheinovement of the lower end of the shaft, and as this movement causes.a slight rocking around the ver- 1 tical axis of the crushing-head itwill .therelfore give a vertical movement to the periphery of thecrushing-head at thebase sufficient to prevent the packing or clingingof Athe material where fine crushing is, desired.

It is obvious that the shorter .the crushinghead the greater theleverage will 4been the material to be crushed, and thatthegreaterthediameter ofthe head the greater will be the vertical movement at itsperiphery.

Of course we do not limit our invention, to the details of constructionof the several parts, as variations may be made in a the structuralfeatures without departing. from the spirit of our invention. Thedrivingbeam may be operatedby means of asingle eccentric. v
